Perhaps your battery performance has decreased. Changing to a new battery will eventually solve the problem?
Source for you to read: The truth about iPhone battery.

if i change the battery, is it okay with the warranty???
because mine is still under warranty...hehehe

thanks again..

Hurm, your iPhone seems to be in it's youth; might no be battery problem. Tell you what, try switch off everything that are not being use such as bluetooth and wifi. Test it for a day or two, see if it changes anything. Sad to say warranty confirm gone if were to unscrew the iPhoney.

If it's till under warranty then just bring in and claim after u test every thing.

you 'd better buy a iphone external power case
very good

Is it original?

That's why i say search in services noticeboard. Some they have original and some have OEM so make sure u ask 1st

Where is it?

Try this http://forum.lowyat.net/topic/920182 He is one of my best technician i have deal with.

so who pays for the data sent out from our iphone each time...must be us, correct??

some applications do auto updates....so if your 3G is on.....does tat mean it will use your 3G to update without notifying you?

Could u tell me what apps do auto updates?

i use ipod and hv itunes on my pc. u use a paid internet security and i notice each time i use the itunes or every other day ( when i do not ) it will auto try to access the internet by itself, my internet security alerts me each time.
so i am guessing for iphones it must be the same.

iPhone App in App store does not auto update so as in Cydia Apps does not auto update as well.

just upgrade to 4.3.2 ..superb ! save a lot battery than before this.. naisss..

4.3.1 and 4.3.2 sometime cannot slide to answer the phone call..
